                  Custom Subscription to Event Streams
             draft-ietf-netconf-subscribed-notifications-08

Abstract

   This document defines capabilities and operations for the customized
   establishment of subscriptions upon a publisher's event streams.
   Also defined are delivery mechanisms for instances of the resulting
   notification messages.  Effectively this allows a subscriber to
   request and receive a continuous, custom feed of publisher generated
   information.
